Jitter in a wireless clock distribution system

The jitter of a transmitted wireless clock signal has been measured and found to behave much like jitter of conventionally distributed clock signals. Noise from nearby digital circuits can degrade receiver sensitivity by reducing LNA gain and shifting the divider self-oscillation frequency. This increases clock jitter and, in extreme conditions, can cause failure in the clock receiver circuits to lock on to the transmitted clock signal. The clock can be re-locked by increasing the transmitted power.
